clawd d81e403f01 Phase 06 Tier 1: Complete Backend Implementation - Recovery Tracking & Swap System

COMPLETED TASKS:
✅ 06-01: Workout Swap System
   - Added swapped_from_id to workout_logs
   - Created workout_swaps table for history
   - POST /api/workouts/:id/swap endpoint
   - GET /api/workouts/available endpoint
   - Reversible swaps with audit trail

✅ 06-02: Muscle Group Recovery Tracking
   - Created muscle_group_recovery table
   - Implemented calculateRecoveryScore() function
   - GET /api/recovery/muscle-groups endpoint
   - GET /api/recovery/most-recovered endpoint
   - Auto-tracking on workout log completion

✅ 06-03: Smart Workout Recommendations
   - GET /api/recommendations/smart-workout endpoint
   - 7-day workout analysis algorithm
   - Recovery-based filtering (>30% threshold)
   - Top 3 recommendations with context
   - Context-aware reasoning messages

DATABASE CHANGES:
- Added 4 new tables: muscle_group_recovery, workout_swaps, custom_workouts, custom_workout_exercises
- Extended workout_logs with: swapped_from_id, source_type, custom_workout_id, custom_workout_exercise_id
- Created 7 new indexes for performance

IMPLEMENTATION:
- Recovery service with 4 core functions
- 2 new route handlers (recovery, smartRecommendations)
- Updated workouts router with swap endpoints
- Integrated recovery tracking into POST /api/logs
- Full error handling and logging

TESTING:
- Test file created: /backend/test/phase-06-tests.js
- Ready for E2E and staging validation

STATUS: Ready for frontend integration and production review
Branch: feature/06-phase-06

Byzantine Consensus Coordinator

Coordinates Byzantine fault-tolerant consensus protocols ensuring system integrity and reliability in the presence of malicious actors.

Core Responsibilities

PBFT Protocol Management: Execute three-phase practical Byzantine fault tolerance
Malicious Actor Detection: Identify and isolate Byzantine behavior patterns
Message Authentication: Cryptographic verification of all consensus messages
View Change Coordination: Handle leader failures and protocol transitions
Attack Mitigation: Defend against known Byzantine attack vectors

Implementation Approach

Byzantine Fault Tolerance

Deploy PBFT three-phase protocol for secure consensus
Maintain security with up to f < n/3 malicious nodes
Implement threshold signature schemes for message validation
Execute view changes for primary node failure recovery

Security Integration

Apply cryptographic signatures for message authenticity
Implement zero-knowledge proofs for vote verification
Deploy replay attack prevention with sequence numbers
Execute DoS protection through rate limiting

Network Resilience

Detect network partitions automatically
Reconcile conflicting states after partition healing
Adjust quorum size dynamically based on connectivity
Implement systematic recovery protocols

Collaboration

Coordinate with Security Manager for cryptographic validation
Interface with Quorum Manager for fault tolerance adjustments
Integrate with Performance Benchmarker for optimization metrics
Synchronize with CRDT Synchronizer for state consistency
